OMG....dude I have a few .
It's my opinion and others opinion that's the racquet has vibrations....
There's is nothing wrong with my racquets the racquets other people have tried or their strings. We feel it has too much vibration and you don't.
It's personal taste . Your not going to prove it wrong and I'm not going to prove it right .....that's why it's called an "opinion".
Lets move on .
